Is your Athlon really running at 2600 MHz? CPDN stresses the CPU and memory subsystem heavier than Seti and instability may result, even though you can successfully run other DC projects.

What is the client error message that you are getting?

exit code -5 usually means the model terminated due to faulty calculations (i.e. unexpected and unrealistic output variable results). This means the model went unstable. This can be due to model parameters, but if it happens persistently, it is usually due to hardware problems when running at 100% CPU and memory intensive.
